Embodiment Construction

[0014] figure 1 It is an exploded diagram of the device. The liquid-liquid extraction device includes three parts: the extraction container 3 , the phase separation adapter 2 and the liquid separation container 1 . 3 is the extraction container, in which the sample and the extraction agent complete the extraction process; 2 is the phase separation adapter, and the phase separation adapter 2 can be tightly connected with the liquid separation container 1 and the extraction container 3, such as figure 2 As shown, when the three are combined, the overall container can be sealed without liquid leakage, and the two-phase solution can complete the liquid separation process through the one-way valve-like structure in the phase separation adapter 2; 1 is the liquid separation container, and the separated heavy phase The solution is stored here. This schematic diagram is only one of the embodiments of the present invention, and is not limited thereto. The capacity of the liquid separ...

Abstract

The present invention provides a liquid-liquid extraction device, and a phase splitting commutator and a liquid-liquid extraction method. The device is composed of an extraction container, a phase splitting commutator and a separating container, combined a seal structure. Wherein, the phase splitting commutator only allows liquid flow to separating container in single direction from the extraction container. Using the device for liquid-liquid extraction does not need liquid transfer tool, the operating step is simple, the extraction yield and the precision of the extracted object are higher.

Description

technical field [0001] The invention relates to a liquid-liquid extraction device, a phase separation adapter used and a liquid-liquid extraction method. Background technique [0002] Liquid-liquid extraction, also known as solvent extraction, is to use the different solubility or distribution ratio of different components in the sample to be distributed in two immiscible solvents to achieve the purpose of separation, extraction or purification, and is widely used in the environment , food, chemical industry, medicine, agriculture and forestry, technological process and many other fields. At present, liquid-liquid extraction is still a powerful method for separating and concentrating trace semi-volatile and certain non-volatile organic compounds in various liquid samples or suspension samples, which other solvent-free extraction techniques cannot. A complete alternative to sample handling techniques. [0003] The traditional method of liquid-liquid extraction requires a va...
